Summary

​Determining how to irrigate more efficiently involves answering several key questions: How do we reduce waterlogging after an irrigation and a rainfall? Can we space out irrigated furrows to reduce waterlogging events and maintain or improve yield? And if so, how far? Researchers rationalized that if corn could be irrigated successfully in shrink swell clay soils, it could lead to better crop rotations. Their objective was to evaluate different furrow irrigation spacings on shrink swell clay soils to reduce waterlogging while maintaining yield. In both on-station and on-farm trials, data showed that yield can be maintained with different furrow irrigation spacings.
